PSoC® Functional Overview
Figure 1. CapSense System Block Diagram
The PSoC family consists of on-chip controller devices, which
are designed to replace multiple traditional microcontroller unit
(MCU)-based components with one, low-cost single-chip
programmable component. A PSoC device includes
configurable analog and digital blocks, and programmable
interconnect. This architecture allows the user to create
customized peripheral configurations, to match the requirements
of each individual application. Additionally, a fast CPU, flash
program memory, SRAM data memory, and configurable I/O are
included in a range of convenient pinouts.

Each CY8C20336H/446H PSoC device includes a dedicated
CapSense block that provides sensing and scanning control
circuitry for capacitive sensing applications. Depending on the
PSoC package, up to 28 GPIOs are also included. The GPIOs
provide access to the MCU and analog mux.

CSCLK
PSoC Core
The PSoC core is a powerful engine that supports a rich
instruction set. It encompasses SRAM for data storage, an
interrupt controller, sleep and watchdog timers, and IMO and
ILO. The CPU core, called the M8C, is a powerful processor with
speeds up to 24 MHz. The M8C is a 4-MIPS, 8-bit Harvardarchitecture microprocessor.
CapSense System
The analog system contains the capacitive sensing hardware.
Several hardware algorithms are supported. This hardware
performs capacitive sensing and scanning without requiring
external components. The analog system is composed of the
CapSense PSoC block and an internal 1-V or 1.2-V analog
reference, which together support capacitive sensing of up to 28
inputs[2]. Capacitive sensing is configurable on each GPIO pin.
Scanning of enabled CapSense pins are completed quickly and
easily across multiple ports.
SmartSense™
SmartSense is an innovative solution from Cypress that removes
manual tuning of CapSense applications. This solution is easyto-use and provides a robust noise immunity. It is the only autotuning solution that establishes, monitors, and maintains all
required tuning parameters. SmartSense allows engineers to go
from prototyping to mass production without re-tuning for
manufacturing variations in PCB and/or overlay material
properties.
IMO
CapSense
Clock Select
Oscillator
Analog Multiplexer System
The analog mux bus can connect to every GPIO pin. Pins are
connected to the bus individually or in any combination. The bus
also connects to the analog system for analysis with the
CapSense block comparator.
Switch-control logic enables selected pins to precharge
continuously under hardware control. This enables capacitive
measurement for applications such as touch sensing. Other
multiplexer applications include:
■
Complex capacitive sensing interfaces, such as sliders and
touchpads.
■
Chip-wide mux that allows analog input from any I/O pin.
■
Crosspoint connection between any I/O pin combinations.
Haptics TS2000 Controller
The CY8C20336H/CY8C20446H family of devices feature an
easy-to-use Haptics controller resource with up to 14 different
effects. These effects are available for use with three different,
selectable ERM modules.
Note
2. 36 GPIOs = 33 pins for capacitive sensing + 2 pins for I2C + 1 pin for modulator capacitor.

Additional System Resources
Getting Started
System resources provide additional capability, such as configurable USB and I2C slave, SPI master/slave communication
interface, three 16-bit programmable timers, and various system
resets supported by the M8C.
For in depth information, along with detailed programming
details, see the PSoC® Technical Reference Manual.
These system resources provide additional capability useful to
complete systems. Additional resources include low voltage
detection and power on reset. The merits of each system
resource are listed here:
Application Notes
■
■
■
■
The I2C slave/SPI master-slave module provides 50/100/400
kHz communication over two wires. SPI communication over
three or four wires runs at speeds of 46.9 kHz to 3 MHz (lower
for a slower system clock).
The I2C hardware address recognition feature reduces the
already low power consumption by eliminating the need for
CPU intervention until a packet addressed to the target device
is received.
The I2C enhanced slave interface appears as a 32-byte RAM
buffer to the external I2C master. Using a simple predefined
protocol, the master controls the read and write pointers into
the RAM. When this method is enabled, the slave does not stall
the bus when receiving data bytes in active mode. For usage
details, refer to the application note I2C Enhanced Slave
Operation - AN56007.
Low voltage detection (LVD) interrupts can signal the
application of falling voltage levels, while the advanced poweron-reset (POR) circuit eliminates the need for a system
supervisor.
■
An internal reference provides an absolute reference for capacitive sensing.
■
A register-controlled bypass mode allows the user to disable
the LDO regulator.
For up-to-date ordering, packaging, and electrical specification
information, see the latest PSoC device datasheets on the web.
Cypress application notes are an excellent introduction to the
wide variety of possible PSoC designs.

Development Tools
PSoC Designer™ is the revolutionary integrated design
environment (IDE) that you can use to customize PSoC to meet
your specific application requirements. PSoC Designer software
accelerates system design and time to market. Develop your
applications using a library of precharacterized analog and digital
peripherals (called user modules) in a drag-and-drop design
environment. Then, customize your design by leveraging the
dynamically generated application programming interface (API)
libraries of code. Finally, debug and test your designs with the
integrated debug environment, including in-circuit emulation and
standard software debug features. PSoC Designer includes:
■
Application editor graphical user interface (GUI) for device and
user module configuration and dynamic reconfiguration
■
Extensive user module catalog
■
Integrated source-code editor (C and assembly)

❐ Hardware and software I C slaves and masters
❐ Full-speed USB 2.0
❐ Up to four full-duplex universal asynchronous receiver/transmitters (UARTs), SPI master and slave, and wireless
PSoC Designer supports the entire library of PSoC 1 devices and
runs on Windows XP, Windows Vista, and Windows 7.
PSoC Designer Software Subsystems
Design Entry
In the chip-level view, choose a base device to work with. Then
select different onboard analog and digital components that use
the PSoC blocks, which are called user modules. Examples of
user modules are analog-to-digital converters (ADCs), digital-toanalog converters (DACs), amplifiers, and filters. Configure the
user modules for your chosen application and connect them to
each other and to the proper pins. Then generate your project.
This prepopulates your project with APIs and libraries that you
can use to program your application.
The tool also supports easy development of multiple configurations and dynamic reconfiguration. Dynamic reconfiguration
makes it possible to change configurations at run time. In
essence, this lets you to use more than 100 percent of PSoC's
resources for an application.
Document Number: 001-56223 Rev. *D
Code Generation Tools
The code generation tools work seamlessly within the
PSoC Designer interface and have been tested with a full range
of debugging tools. You can develop your design in C, assembly,
or a combination of the two.
Assemblers. The assemblers allow you to merge assembly
code seamlessly with C code. Link libraries automatically use
absolute addressing or are compiled in relative mode, and linked
with other software modules to get absolute addressing.
C Language Compilers. C language compilers are available
that support the PSoC family of devices. The products allow you
to create complete C programs for the PSoC family devices. The
optimizing C compilers provide all of the features of C, tailored
to the PSoC architecture. They come complete with embedded
libraries providing port and bus operations, standard keypad and
display support, and extended math functionality.
Debugger
PSoC Designer has a debug environment that provides
hardware in-circuit emulation, allowing you to test the program in
a physical system while providing an internal view of the PSoC
device. Debugger commands allow you to read and program and
read and write data memory, and read and write I/O registers.
You can read and write CPU registers, set and clear breakpoints,
and provide program run, halt, and step control. The debugger
also lets you to create a trace buffer of registers and memory
locations of interest.
Online Help System
The online help system displays online, context-sensitive help.
Designed for procedural and quick reference, each functional
subsystem has its own context-sensitive help. This system also
provides tutorials and links to FAQs and an Online Support
Forum to aid the designer.
In-Circuit Emulator
A low-cost, high-functionality in-circuit emulator (ICE) is
available for development support. This hardware can program
single devices.
The emulator consists of a base unit that connects to the PC
using a USB port. The base unit is universal and operates with
all PSoC devices. Emulation pods for each device family are
available separately. The emulation pod takes the place of the
PSoC device in the target board and performs full-speed
(24 MHz) operation.

CY8C20336H, CY8C20446H
Designing with PSoC Designer
The development process for the PSoC device differs from that
of a traditional fixed-function microprocessor. The configurable
analog and digital hardware blocks give the PSoC architecture a
unique flexibility that pays dividends in managing specification
change during development and lowering inventory costs. These
configurable resources, called PSoC blocks, have the ability to
implement a wide variety of user-selectable functions. The PSoC
development process is:
1. Select user modules.
2. Configure user modules.
3. Organize and connect.
4. Generate, verify, and debug.
Select User Modules
PSoC Designer provides a library of prebuilt, pretested hardware
peripheral components called “user modules.” User modules
make selecting and implementing peripheral devices, both
analog and digital, simple.
Configure User Modules
Each user module that you select establishes the basic register
settings that implement the selected function. They also provide
parameters and properties that allow you to tailor their precise
configuration to your particular application. For example, a PWM
User Module configures one or more digital PSoC blocks, one
for each eight bits of resolution. Using these parameters, you can
establish the pulse width and duty cycle. Configure the parameters and properties to correspond to your chosen application.
Enter values directly or by selecting values from drop-down
menus. All of the user modules are documented in datasheets
that may be viewed directly in PSoC Designer or on the Cypress
website. These user module datasheets explain the internal
operation of the user module and provide performance specifications. Each datasheet describes the use of each user module
parameter, and other information that you may need to successfully implement your design.
Document Number: 001-56223 Rev. *D
Organize and Connect
Build signal chains at the chip level by interconnecting user
modules to each other and the I/O pins. Perform the selection,
configuration, and routing so that you have complete control over
all on-chip resources.
Generate, Verify, and Debug
When you are ready to test the hardware configuration or move
on to developing code for the project, perform the “Generate
Configuration Files” step. This causes PSoC Designer to
generate source code that automatically configures the device to
your specification and provides the software for the system. The
generated code provides APIs with high-level functions to control
and respond to hardware events at run time, and interrupt
service routines that you can adapt as needed.
A complete code development environment lets you to develop
and customize your applications in C, assembly language, or
both.
The last step in the development process takes place inside
PSoC Designer's Debugger (accessed by clicking the Connect
icon). PSoC Designer downloads the HEX image to the ICE
where it runs at full-speed. PSoC Designer debugging capabilities rival those of systems costing many times more. In addition
to traditional single-step, run-to-breakpoint, and watch-variable
features, the debug interface provides a large trace buffer. It lets
you to define complex breakpoint events that include monitoring
address and data bus values, memory locations, and external
signals.

Figure 8. Definition for Timing for Fast/Standard Mode on the I2C Bus
Note
20. A Fast-Mode I2C-bus device can be used in a Standard Mode I2C-bus system, but the requirement tSU;DAT  250 ns must then be met. This automatically be the case
if the device does not stretch the LOW period of the SCL signal. If such device does stretch the LOW period of the SCL signal, it must output the next data bit to the
SDA line trmax + tSU;DAT = 1000 + 250 = 1250 ns (according to the Standard-Mode I2C-bus specification) before the SCL line is released.

Numeric Naming
Hexadecimal numbers are represented with all letters in
uppercase with an appended lowercase ‘h’ (for example, ‘14h’ or
‘3Ah’). Hexadecimal numbers may also be represented by a ‘0x’
prefix, the C coding convention. Binary numbers have an
appended lowercase ‘b’ (for example, 01010100b’ or
‘01000011b’). Numbers not indicated by an ‘h’, ‘b’, or 0x are
decimal.

Glossary
Crosspoint connection
Connection between any GPIO combination via analog multiplexer bus.
Differential non-linearity
Ideally, any two adjacent digital codes correspond to output analog voltages that are exactly
one LSB apart. Differential non-linearity is a measure of the worst case deviation from the
ideal 1 LSB step.
Hold time
Hold time is the time following a clock event during which the data input to a latch or flipflop must remain stable in order to guarantee that the latched data is correct.
I2C
It is a serial multi-master bus used to connect low speed peripherals to MCU.
Integral nonlinearity
It is a term describing the maximum deviation between the ideal output of a DAC/ADC and
the actual output level.
Latch up current
Current at which the latch up test is conducted according to JESD78 standard (at 125 °C)
Power supply rejection ratio (PSRR) The PSRR is defined as the ratio of the change in supply voltage to the corresponding
change in output voltage of the device.
Scan
The conversion of all sensor capacitances to digital values.
Setup time
Period required to prepare a device, machine, process, or system for it to be ready to
function.
Signal-to-noise ratio
The ratio between a capacitive finger signal and system noise.
SPI
Serial peripheral interface is a synchronous serial data link standard.
